The PXC5.E24 is the latest automation station from Siemens to be added to the Desigo HVAC and building control system.
A fundamental requirement for efficient building automation is a reliable control system. The new controller joins the existing PXC4 and PXC7 controllers and features 24 onboard I/Os, which can be extended to offer 80 points on a single compact unit.
Siemens says that the PXC5.E24 is designed for optimum interoperability, with its two RS485 ports, enabling Modbus data point integration via RTU and the BACnet open communication protocol. It also features an onboard KNX PL-Link, making daisy-chain network extension easy, with M-Bus integration available soon.
Quick installation and commissioning are ensured through a simple and intuitive license-free ABT Site engineering tool, supported by the ABT Go mobile app, allowing connectivity from a smartphone. A further benefit in terms of installation is that the controller can provide power for up to four extension I/O modules from the TXM I/O range.
Secure remote connectivity offers the capability to monitor and make changes to the system off-site, reducing the potential number of site visits and improving sustainability. Alarms can be processed on-site or remotely through the user’s wireless access to the controller. Security is a central feature of the design, with certificate handling and signed firmware to prevent cyber-attacks from malware and viruses.
Desigo is designed to manage any facility, irrespective of its size or complexity and, according to Siemens, enhances occupant comfort and productivity.
